APPARATUS FOR REGULATING THE TEMPERATURE OF MILK OR CREAM VATS.

SPECIFICATION forming part of Letters Patent No. 348,016, dated August24, 1886.

Application filed May 21, 1886. Serial No.202,932.

of which the following is a specification.

My invention consists in an improved apparatus for regulating thetemperature of the water in milk-vats, by introducing steam, in themanner hereinafter described, into the pipes through which the watercirculates, the apparatus being so constructed and arranged that thesteam enters the water in the outer vats, mingled with the water whichcirculates through the pipes, so that the steam makes no noise whenescaping from these pipes into the vats, while the circulation throughthe vats can be readily controlled, and thewater, hot or cold, can beutilized for washing and cleansing milk-cans and other vessels, and forother purposes, all as will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure l is a perspective viewshowing my improved apparatus in its operative position, and Fig. 2 is atop plan view thereof.

The same letters of reference indicate corresponding parts in all thefigures.

Referring to the several parts by letter, A and B represent the largeouter wooden vats or tanks, which are usually employed in a creamery,and within these outer vats are set the tin milk-vats O O, in which themilk is contained, these tin vats being surrounded by water, which fillsthe outer vats to the requisite height.

In the lower portion of one end of each outer tank, A B, is .insertedthe inner portion of a suction-pipe, D E, that portion of thesuctionpipe E immediately outside of the vat B' being formed of aflexible rubberhose, B, which admits of the suction-pipe E being readilywithdrawn from the vat B and inserted in another vat when required. Theouter ends of the suction-pipes D E communicate with one end of aconnecting-pipe, F, which communicates near its other end with twodischarge-pipes,

-G and H, the discharge-pipe G discharging into the lower portion of theopposite end of the vat A from that end into which the suc- (No model.)

tion-pipe D leads, while the discharge-pipe H discharges into thecorresponding end of the second vat, B, that portion of the pipeHimmediately outside of the vat B being formed of flexible rubber hoseH, to admit of the .removal of this dischargepipe and its adjustmentinto another vat.

The outer ends of the suction and discharge pipes are provided, near thepoints where they communicate with the connecting-pipe F, with thecontrolling-valves I J K L, and that end of the connecting-pipe whichIwill denominate the forward end is provided with a similar valve, M,and has connected to it, immediately in advance of the said valve, theflexible hose N, for the purpose hereinafter specified.

In the central portion of the connectingpipe F, I place my improvedinjector O, for which Letters Patent No. 121,376 were granted to me,hearing date of November 28, 1871, although I do not wish to confinemyself to this specific form of injector, as any other suitable form ofinjector may be employed, and the steam-pipe O of the injector, throughwhich steam is introduced into the connecting-pipe Ffrom the boiler, isprovided with the valve I, which controls the entrance of steam into theconnecting-pipe F.

The operation of my improved apparatus is as follows The valve M at theforward end of the connecting-pipe F is normally closed, and the valvescontrolling the suction and discharge pipes having been opened, thewater from the large outer vats, A B, will enter the said pipes and flowinto the connecting-pipe F. In order to create a circulation and heatthe water to the requisite temperature the valve P of the steam-pipe Ois opened to the desired extent, when the steam passing through theinjector toward the forward end of the connecting-pipe F is thoroughlymingled by the injector with the water in the said pipe,

and will force this water with which it is mingled out through thedischarge-pipes into the forward ends of the vats, and thereby createasuction through the suction-pipes into the rear end of theconnecting-pipe, and this operation continuing will cause a perfectcirculation through the tanks or vats, the suctionpipes, theconnecting-pipe, and the dischargepipes, the water being heated by thesteam to any desired degree of heat.

It will be seen that by thus mingling the steam with the water in thepipes before it escapes therefrom into the vats the steam will enter thevats without the slightest noise or disturbance.

It will be seen that by closing the cocks of the suction and dischargepipes of either one of the vats the circulation can be confined to onevat, while by closing the valve of the suction-pipe of one vat andclosing the valve of the discharge-pipe of the other vat the watercan betransferred from one vat to the other with great ease, the steam fromthe boiler acting as the motive power.

By opening one or both of the valves of the suction-pipes and closingthe valves of the discharge-pipes, and also opening the valve M at theforward end of the connecting-pipe F, the apparatus will operate as asteam-pump to throw either hot or cold water through the flexible hose Nto any part of the building, which is very convenient for cleaning thechurns and other vessels around the creamery.

From the foregoing description, taken in connection with theaccompanying drawings,

the construction, operation, and advantages of my improved apparatuswill be readily understood. It will be seen that by its usea perfectcirculation of the water at as high or low degree of temperature asdesired is obtained, while the circulation can be confined to one vat,if desired, or water can be transferred from one vat to another, and theapparatus may be further employed, as described, as a steam-pump formany useful purposes. The steam escapes noiselessly and without theleast disturbance,whieh is a very important point.

My improved apparatus is very simple in construction, and therefore notliable to get out of order in any way,while at the same time it is veryeflicient in its operation for the various purposes for which it isdesigned.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The eombinatiomwith the outer vat and the milk receptacles or vatsseated therein, of thesuction-pipeleadingfrom oneend of the said outervat, the'discharge-pipe leading into the other end of the said vat, thepipe connecting b the outer ends of these two pipes, and the steam pipeprovided with the regulatingvalve, and having the forwardly-inclined endarranged, as described,within the central portion of theconnecting-pipe, as and for the purpose set forth.

2. The combination, with the outer vat and the milk receptacles or vatsseated therein, of thesuction-pipe leading from one end of theouter vat,aud'having the valve near its outer end, the discharge-pipe leading intothe other end of the outer vat, and having the valve near its outer end,the pipe connecting the outer ends of these two pipes, and having thevalve at its forward open end, and the steam-pipe provided with theregulating-valve, and having the forwardlydnelined end arranged, asdescribed, within the central portion of the connectingpipe, as and forthe purpose set forth.

3. The eombination,with the outer vats and the milk receptacles or vatsseated therein, of the suction-pipes from one end of the said outervats, and each having the valve near its outer end, the discharge-pipesleading into the forward ends of the outer vats, and having the valvesnear their outer ends, the pipe connecting the outer ends ofthedischarge-pipes and suction-pipes, and having at its forward end thevalve and the flexible hose, and thesteampipe provided with theregulating-valve, and having the forwardly-inclined end arranged, asdescribed,within the central portion of the connecting-pipe, allconstructed and arranged to operate in the manner and for the purposeherein set forth.
